DocIndexRetriever/tests/README.md:6

• [nitpick] The name HF_TOKEN may be too generic; consider renaming to HF_API_TOKEN or HF_HUB_TOKEN for greater clarity.

export HF_TOKEN="Your_Huggingface_API_Token"

DocIndexRetriever/tests/test_compose_without_rerank_on_xeon.sh:42

• Add a check to verify that set_env.sh exists and that HF_TOKEN is set after sourcing, e.g. [[ -f set_env.sh ]] || exit 1 and [[ -n "$HF_TOKEN" ]] || { echo 'HF_TOKEN not set'; exit 1; }.

source ./set_env.sh

DocIndexRetriever/docker_compose/intel/hpu/gaudi/set_env.sh:14

• Consider validating HF_TOKEN at the top of this script to fail fast if the variable is undefined or empty.

export HF_TOKEN=${HF_TOKEN}
